Context History (more history, all contexts)

Start Date Context Status Description
2022-05-04 hst_1011.pmap operational This new bad pixel table, USEAFTER March 16, 2022, was generated using data taken from March 16, 2022 through April 12, 2022. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of Feb 19, 2022. The automated pipeline should now use these reference files as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because they represent the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bpx files were generated using 900 second dark exposures from the HST Cycle 29 daily monitoring programs 16564, and 16567. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14.
2022-05-03 hst_1010.pmap archived Delivering a new ACS BIASFILE rmap to change pre-SM4 WFC full-frame entries to use a CCDAMP value of ABCDALL instead of ABCD to allow for consistency between pre- and post-SM4 BIASFILE selection. The affected BIASFILEs will be delivered at a later time with this change reflected in their headers.
2022-05-03 hst_1009.pmap archived COS FUV observations at LP6 consist of separate SWAVE wavecal exposures that occur on a location on the detector that is approximately 28 pixels below the location of the LP6 PSA. Therefore, we have edited the XTRACTAB such that proper extraction of these wavecals can occur.
2022-05-02 hst_1008.pmap archived The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on Apr 28, 2022, and should be used to calibrate ACS WFC observations taken between Mar 28, 2022 and Apr 28, 2022.
